Check if two Bundle objects are equal in Android?

Question

I would like to check if two bundles are equal, is there any way to do that instead of checking them key by key?

Answer 1

I have tested Sam's answer and it contains a flaw. Plus I am loving Kotlin at the moment, so here is my version.

• Again the keys sets need to be the same size
• The key sets need to have the same values
• If both values are Bundle then test recursively.
• Otherwise test values for equality (don't retest bundles)

Code:

fun equalBundles(one: Bundle, two: Bundle): Boolean {
    if (one.size() != two.size())
        return false

    if (!one.keySet().containsAll(two.keySet()))
        return false

    for (key in one.keySet()) {
        val valueOne = one.get(key)
        val valueTwo = two.get(key)
        if (valueOne is Bundle && valueTwo is Bundle) {
            if (!equalBundles(valueOne , valueTwo)) return false
        } else if (valueOne != valueTwo) return false
    }

    return true
}

Answer 2

private static boolean equalsBundles(Bundle a, Bundle b) {
        Set<String> aks = a.keySet();
        Set<String> bks = b.keySet();

        if (!aks.containsAll(bks)) {
            return false;
        }

        for (String key : aks) {
            if (!a.get(key).equals(b.get(key))) {
                return false;
            }
        }

        return true;
    }
